I do not believe that the PNA-X currently supports option 551, so I will assume that you are using a 4 port N5230A PNA-L with the 12 port extension test set (U3042AE12) with option 551 enabled.

You would go through guided cal make sure that the ecal module was selected for each port. Then you would perform at least 15 2 port ecals to complete a 16 port cal. With the N4431A/31B/2A/3A ecal module you would perform at least 5 4 port ecals to complete a 16 port cal.

Hi, not to put too fine a point on it, but you need 16 1 port cals, and 15 "unknown-thru" measurements. In practice, if you use an ecal, you make the 15 through connections and the analyzer does 2 port cals during each step. But for mechanical cal kits, it only makes you do the 1 port cal once for each port.

An alternative is to setup your 16 ports to have one port that is insertable, and do one 1-port cal, and 15 "known-thrus". I think this will work.

As for 551 on the PNA-X, just a matter of time and QA. I think it might work now on 7.22.01 but is not fully QA'd so it isn't listed for sale.

Hi O.J., I'm indeed using a PNA-X with the opt.423, now one customer wanna inquire about the 16 port cal with the N4691-60001 ecal, so I ask this question here.many thanks for ur reply.
